2/3 of all Q2 U.S. phone sales involved smartphones, according to Nielsen - a figure that demonstrates most of the market's growth is now tapped out, and emerging markets such as China will have to pick up the slack. Android (GOOG) made up 54.6% of sales, and the iPhone (AAPL) 36.3%. In spite of the Lumia 900 (NOK) launch, Windows Phone (MSFT) accounted for just 1.7% of sales, while BlackBerry (RIMM) devices made up a paltry 4%.
